An object of the invention is to provide a device to hold a casement window open at various positions.

Another object of the invention is to provide an attachment for a casement window assembly for retaining the window in a selected open position effectively and easily. The attachment may be used in addition to or in lieu of other devices for achieving the same results, for instance the conventional operating mechanisms of casement windows, regardless of the type of conventional operating mechanisms.

One of the problems encountered in the use of casement windows is glass breakage due to high winds which cause the casement window to slam to a closed or full open position. This difficulty is obviated by the invention and in a very simple way.

Briefly, the invention is embodied in a bracket with what are considered to be unique means to secure one end of the bracket to the casement window casing and with unique means to engage the edge of the window frame to hold the frame and consequently, the entire window panel in a selected open position.

An important feature of the invention is found in its simplicity of construction and in the comparative cheapness of production cost. It is made of a single piece of wire or of metallic stock of different cross-sectional shapes. One end of the main body of the device is formed with a plurality of coils, similar to a coil spring, and these grip an edge of the window frame either at the top, the bottom, or along one side thereof, preferably the latter. The main body has a number of pockets in it, and each establishes a separate station at which the window panel may be locked.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of a device exemplifying the invention.

FIGURE 2 is a horizontal sectional view of a conventional casement window equipped with one of the locking devices.

In the accompanying drawings there is a conventional casement window made of a window panel 12 connected by hinge 14 to window frame 16 at an edge thereof. The window panel is glazed as at 18 and has a window frame 20 provided with an outwardly extending flange 22. This is conventional construction.

Window frame 16 is also conventional and therefore it includes a bottom rail or strip 24, a parting strip 26 and a side 28. In single window installations, parting strip 26 is merely a side identical to side 28. Ordinarily, the conventional frame 16 is essentially a channel in section and therefore the illustration in FIGURE 2 follows such a pattern.

Device 30 is an attachment to be used in lieu of or in addition to the conventional operating mechanism for window panel 10. The device very firmly and securely holds the window panel in a selected open position. It consists of a main body 32 and means 34 at one end thereof for gripping and holding side 28 of frame 16. Main body 32 is made of an elongate elastic aind resilient member, for example metal which has a degree of resilience and elasticity. Means 34 consist of a pluralityof coils 36 formed at one end of main body '32. The'coils are resilient and have an appearance of a conventional spring. Actually, they are the components of the spring and engage the flanges 27 and 29 of side 28. The flanges of the channel-shaped side 28 are received between adjacent coils 36, and the inherent resilience in the material from which the coils are made cause a frictional engagement to exist between the coils and the flanges 27 and 29 thereby supporting the main body 32 on the side 28. For additional support, coils 36 may be used at the juncture of bottom 24 and side 28. Further, it is to be noted at this point that although one device 30 is shown used with window 10, two or more may be used without departing from the invention.

There are means in main body 32 along the length thereof for engaging flange 20 and thereby holding window panel 12 in a selected open position. These means consist of a number of spaced pockets 40 along the length of the main body 32. Each pocket is formed by an essentially U-shaped portion 42 of the main body, and all the pockets open toward one side of the main body 32. The inherent resilience of the main body enables it to be deflected outwardly i.e. away from flange 22 so that the window panel may be swung between the open and closed positions. However, when the desired opening is established, the main body 32 is released so that the inherent resilience and elasticity thereof causes it to spring back to its normal position at which flange 22 enters a selected pocket 40. In the construction of device 30, the main body which is made of spring steel or other suitable metal having the necessary degree of elasticity and resilience, is fonned in an are so that the pockets 40 will be presented to flange 22 properly at all stations between the fully opened and fully closed positions of the window panel.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A self-contained readily attachable and detachable stay for a casement window that is hingedly mounted in a window mounting frame comprising a longitudinally curved arm, said arm being flexibly resilient, means spaced along the length of said arm for engaging an edge portion of the window frame, and spring means connected with an end of said arm serving to mount said arm on the window mounting frame, said first named means including a plurality of keeper pockets with which a portion of one edge of the frame of said window is adapted to be received and held.

2. The structure defined in claim 1 and wherein said arm mounting means comprises a plurality of coils at one end of the arm and which are adapted to frictionally grip the window frame.

3. For use in temporarily retaining a hinged casement window ajar in respect to a relatively stationary mounting frame on which it is hingedly mounted; a readily applicable and removable stay comprising a springy steel rod arcuately bowed and having a curvature generally conformable to the arc of the path through which a free swinging marginal edge portion of the casement window is constrained to travel toward and from said mounting frame, said rod embodying an inward attaching and supporting end having spring coils adapted to resiliently and releasably grip existing flanges provided on a vertical References Cited in the file of this patent UNITED STATES PATENTS Neubauer et al.
